Abstract (en)
New aldimine compounds are claimed. Aldimine compounds of formula ((HX) m-A-(N=CH-C(R 1>)(R 2>)-CH(R 3>)-N(R 4>)(R 5>)) n) (I), are new. Either A : an amine residue after removing n primary aliphatic amino group and m HX group; or A together with R 7> : (n+2)-valent 3-20C-hydrocarbon, which optionally contains at least a heteroatom, preferably in the form of an ether oxygen or tertiary amine nitrogen; either n : 1-4, preferably 1 or 2; and m : 0-1; or m+n : 2-5; either R 1>, R 2> : univalent 1-12C-hydrocarbon; or R 1>R 2> : a bivalent 4-12C-hydrocarbon, whose one part is optionally substituted by 5-8C, preferably 6C carbocyclic ring; R 3> : H or 1-12C-alkyl, -arylalkyl or alkoxycarbonyl; R 4>, R 5> : univalent 1-20C-aliphatic, -cycloaliphatic or -arylaliphatic atoms, which is free of OH and optionally contains heteroatom in the form of ether-oxygen or tertiary amine nitrogen; R 4>R 5> : a bivalent 3-20C-aliphatic atoms, whose one part is optionally substituted by heterocyclic ring 5-8, preferably 6, ring atoms, where the ring is free of OH and contains optionally further heteroatom in the form of ether oxygen or tertiary amine nitrogen, adjacent to the nitrogen atom; X : O, S, NR 6>or NR 7>; R 6> : univalent 1-20C-hydrocarbon, which optionally contains at least a carboxylic acid ester-, nitrile-, nitro-, phosphonic acid ester-, sulfone or sulfonic acid ester group, or (-B 1>-(N=CH-C(R 1>)(R 2>)-CH(R 3>)-N(R 4>)(R 5>)) p) (II); p : 0-10000; and B 1> : (p+1)-valent hydrocarbon, which contains optionally an ether-oxygen, tertiary amine nitrogen, OH, secondary amino or mercapto. Independent claims are included for: (1) another aldimine compound of formula ((HX 2>) m-A-(N=CH-C(R 1>)(R 2>)-CH(R 3>)-N +>(R 10>)(R 4>)(R 5>)) n) (IX), obtained by protonating or alkylating (I); (2) the preparation of (I); (3) the preparation of an aldehyde compound of formula (O=CH-C(R 1>)(R 2>)-CH(R 3>)-N(R 4>)(R 5>)) (IV) obtained from an aldehyde formula (O=CH-CH(R 1>)(R 2>)) (V) or (O=CH-CH-R 3>) (VI), a secondary aliphatic amine of formula (NH-R 4>-R 5>) (VII), preferably dimethylamine, diethylamine, diisopropylamine, dibutylamine, diisobutylamine, N-methylcyclohexylamine, N-methyl-benzylamine, N-isopropyl-benzylamine, N-tert.butyl-benzylamine, dibenzylamine, pyrrolidine, piperidine, morpholine or 2,6-dimethylmorpholine; (4) an aldimino group containing compound (VIII) obtained by reacting (I) (in which m is 1) with at least a compound (IX) containing a reactive group, which can undergo addition reaction with the HX group in (I); and (5) a hardenable composition comprising (I) or (VIII) and at least a polyisocyanate. R 10> : H or 1-20C-alkyl, cycloalkyl or arylalkyl; X 2> : O, S, NR 11>or NR 7>; and R 11> : univalent 1-20C-hydrocarbon, which optionally contains at least a carboxylic acid ester, nitro, nitrile, phosphonic acid ester, sulfone or sulfonic acid ester, or (-B 1>-(N=CH-C(R 1>)(R 2>)-CH(R 3>)-N +>(R 10>)(R 4>)(R 5>)) p) (IXa).
Abstract (de)
Gegenstand der vorliegenden Erfindung sind in einem ersten Aspekt Aldimine der Formel (I). Diese Aldimine eignen sich insbesondere als latente Härter in härtbaren Zusammensetzungen, insbesondere in ein- oder zweikomponentigen Isocyanatgruppen aufweisenden Zusammensetzungen. Sie lassen sich aufgrund der vorhandenen reaktiven Gruppe zu Aldimingruppen-haltigen Verbindungen der Formel (X) und (XII) umsetzen, welche ein weiterer Aspekt der vorliegenden Erfindung darstellt. Die Aldimine, bzw. die Aldimingruppen-haltigen Verbindungen, lassen sich vor allem in Kleb- und Dichtstoffe, aber auch in Beschichtungen verwenden und lassen sich leicht aus gut erhältlichen Grundstoffen herstellen und weisen eine gute thermische Stabilität auf. Ihre tertiäre Aminogruppe weist eine überraschend niedrige Basizität auf und kann unter Umständen in chemischen Reaktionssystemen eine katalytische Wirkung entfalten.
